FLUSHlNG-TANK.

SPECIFICATION forming part of Letters Patent No. 769,525, dated September 6, 1904.

Application filed July 10,1903.

To all whom it 7ll/ll l/ concern:

Be it known that I, OTTO ADAMS, a citizen of the United States, residing in the borough of Queens, in the county of Queens, city and State of New York, have invented a new and useful Improvement in Flushing-Tanks, of i which the following is a specification.

My invention pertains to flushing-tanks or tanks which are used to receive and contain water which may be used to flush or cleanse the bowls of latrines or sinks.

An object of my invention is to provide a j flushing-tank which shall be so constructedas to cause its contents to be precipitated under 1 much greater pressure, and consequently with greater force and elfect, than'attend the gravitational precipitation of water as from ordinary tanks.

Another object of my invention is to provide a flushing-tank which shall be so constructed that a relatively small quantity of water which may be precipitated therefrom shall operate as effectually as a relatively large body of water which may be gravitationally precipitated as from an ordinary tank, a considerable saving of water being thus effected by the use of my invention.

Still another object of my invention is to provide a flushing-tank which because of the sutficiency of its operation with a relatively small quantity of water may itself be of rela tively small dimensions, and thus require a relatively small amount of space for its occupancy.

In the drawings, Figure l is a vertical longitudinal section of a tank which embodies a form of my invention, the section being taken on the line a z Fig. 2; and Fig. 2 is a top plan view thereof.

Reference characters are relatively alike throughout the drawings.

Referring to the drawings, 1 designates a tank, which may be made of any suitable material, the form illustrated in the drawings being that of a tank which is made integrally of cast metal which is suitably cored in the founding thereof and thereafter machined to fit parts which are to be mounted thereon. The

tank 1 is closed on all sides and may be pro- Serial No. 164,940- No modal.)

l vided with ears by which it maybe suspended in position for use. The upper wall of the tank 1 is perforated, the perforation being screw-tlu-eaded to engage a screw-threaded shoulder of a tube 2, which projects downwardly into the tank 1 and is furnished with a perforated cap 2, which may be suitably formed to be engaged by a wrench. The tube 2 comprises two parts 2 2", which should be dimensionally different diametrally, the upper part 2' being larger than the lower part 2.

Alined with the tube 2 and projecting from l the lower part of the tank 1 is a cylindriform outflow-pipe formed as a pipe-couplings, and l at the upper end thereof is fixed a valve-seat a. and in the pipe at is a perforated guide L for the stem 5 of a water-valve 5, which is adapted to fit on the seat a and which is fixed upon the lower end of a valve-rod 6, on which is lixed an air-valve T, which is preferably formed as a leather annulus and is adapted to fit air-tightly in the part 2 of the tube 2. It should be noted that in use the air-tightness l of the valve 7 is readilymaintained by reason l of its being continually kept in a moist condition, as will be hereinafter set forth.

The valve-rod 6 extends upwardly through l the cylinder 2 and through the perforation in l the cap 2, and the upper end of said rod is l bifurcated, as at (5, to admit one end of a lever 8, which is slotted, as at 8, where it is cross-pinned to the valve-rod (3. The lever 8 is fulcrumed on a bracket 8, which atits opposite end may be swiveled on the cap 2 and be secured in place on said cap by any suitl able rneans such, for instance, as a set-screw. (Not shown.) An air-vent 2 may be formed l in the upper part of the tube 2, or the rod 6 may be loosely titted in the cap 2 in order l to form an air-vent between said members for a purpose hereinafter related. A chain l l l l 9 may be attached to the outward end of the lever 8 and descending thence may be manually operated to rock said lever and by means thereof to open the water-valve 5 and the airvalve 7. A helical spring 10 may encompass the rod 6 and contact at one end the cap 2 and at the other end an adjustable nut 11, l which is mounted on the rod 6, and by means 7 may be urged downwardly to their func 6 and valves 5 and l of said spring 10 the rod tionally-efl'ective positions. A water-supply pipe 12 is shown tapped into the lower wall '1 of the tank 1 to admit water (herein referred to as 14:) into the tank 1. A check-valve 13 may be inclosed in the supply-pipe 12 to prevent the water 14 from flowing out of the tank 1 through said pipe. The operation and advantages of my in- 1 vention may be readily understood and appreciated. The tank 1 should be properly positioned relatively of the bowl which is to be i cleansed or flushed. A service-pipe should then be coupled to the supply-pipe 12, and by d means thereof water should be admitted into the tank 1 and permitted to continue to flow thereinto until the pressure thereof is equaled by the pressure of the air which is confined in the tank 1, which latter will remain airtight when not operating to flush the bowl. When the before-mentioned bowl is to be flushed, the chain 9 is pulled downwardly, and by means thereof and of the lever 8 the valve-rod 6 will be moved upwardly, thus raising the valve 5 from the valve-seat 1. Thereupon, impelled by gravity and by the pressure of the air which has been compressed in the tank 1 by means of the inflow of water 14:, the latter passes through thevalve-seat 4: and coupling 4 and may be led i to the before-mentioned bowl by any suitable 1 means. (Not shown.)

It should be noted that primary moving impulse is communicated to the outfiowing 1 water before the valve 7 has passed out of the part 2 of the tube 2. Continued upward movement of the rod 6 causes the valve 7 to pass, as aforesaid, from the part 2 of the tube to the part 2 thereof, and thus by means of the before-mentioned air-ventas,-for instance, between the respective surfaces of the cap 2 and rod 6--vents the tank 1, thus preventing the production of a partial i Vacuum in the tank 1, obviating any back pressure on the outfiowing water and permitting the latter to flow until the chain 9 is released, when, as will readily be seen, the rod 6 Will be urged downwardly by the spring 10 and the valves 5 and 7 will be returned to their respective efl e ctive prime positions.

It should be clearly noted that water flowing as related from the tank 1 will be primarily moved by gravitation plus the pressure of the air which is compressed by means of the previous inflow of water and that thereafter and until the outflow thereof ceases the rate of movement of the outfiow will be continually increased gravitationally and will therefore from the commencement to the end of the outflow be greater than the rate of movement of an outflow which is primarily established by gravitation only.

The air-pressure which will be established I in the tank 1 will be maintained therein until released, as before related, regardless of any other fiow of water from the service-pipe as the check-valve through the supwhich supplies said tank, 13 will prevent any backflow ply-pipe 12.
